lm_sensors not working with Zabbix in kernel 2.6

[cybermage]

because /proc/sys/dev/sensors are no more in 2.6 kernel

Based on http://www2.lm-sensors.nu/~lm78/read...gi?ticket=2028

new path is /sys/bus/i2c

Just FYI

lm-sensors and Kernel 2.6

is there any solution or workaround ?

thank your

a bit crude workaround would be userparameter parsing 'sensors' output

Lmsensors and net-snmp

An elegant solution to monitor lm_sensors with zabbix could be compile net-snmp with lmsensors support.

Instructions at http://www.net-snmp.org/docs/README.solaris.html

Lmsensors is under oid 1.3.6.1.4.1.2021.13.16

Temperatures should be divided by 1000 to be correctly presented in zabbix.

Table identifiers might be different on your computer. Take a look at mine:

snmptable localhost -c public -v 1 1.3.6.1.4.1.2021.13.16.2
SNMP table: LM-SENSORS-MIB::lmTempSensorsTable

 lmTempSensorsIndex lmTempSensorsDevice lmTempSensorsValue

                 3               fan4                 0

snmptable localhost -c public -v 1 1.3.6.1.4.1.2021.13.16.5

                 12              Core 1              73000
                 13              Core 2              51000
                 14              Core 3              73000

Another crude workaround could be extending zabbix agent like this

UserParameter=sensors[*],sensors | grep "$1" | head -$2 | tail -1 | awk '{print $"$3"}' | sed 's/[-!@#\$%^&*()°+a-zA-Z]//g'

Example of usage
sensors[fan2,1,2] – Would get the value in the first ocurrance of string fan2, with the value in the second column.

sensors[Core,4,3] – Would get the value in the fourth ocurrance of string "Core", with the value in the third column. Another way to get the same data could be
sensors[“Core 3”,1,3] – Would get the value in the first ocurrance of string "Core 3", with the value in the third column.

sensors[String that identify the sensor, Nth ocurrance of the string that identify the sensor, Column]

Obs: Columns are separated by one or more spaces.
